BINDING ATTACHMENT FOR BALlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 496,628, dated May 2,1893.

Application filed April 20, 1889. Serial No. 308,021- (No model.)

To aZZ whom it may concern:

Be it known that I, ANDREW WIOKEY, of Quincy, in the county of Adams andState of Illinois, have invented certain Improvements in BindingAttachments for Baling-Presses, of which the following is aspecification.

This invention has reference to that class of presses in which thematerial is delivered in rapidly succeeding charges into one end of atrunk or chamber, the charges compressed against the preceding mass, theslowly advancing mass divided at suitable intervals into bales, andthese bales delivered in succession in the open end of the trunk.

The invention relates to improved means for automatically binding thebales with wire previous to their delivery. With-the exception of thebinding mechanism the press may be in all respects of ordinaryconstruction, and in the drawings I have represented the improvementsapplied to a press of the type represented in numerous Letters-Patentheretofore granted to me.

The details of the mechanism for feeding the press and for operating thefollower or plunger are omitted as they form no part of my invention.

In the accompanying drawings,Figure 1 isa side elevation of the body ortrunk of the press with my improvements applied thereto. Fig. 2 is anelevation of the same from the opposite side. Fig. 3 is a cross-sectionon the line -00 of the preceding figure. Fig. 4 is a perspective view ofone of the needles for passing the wire around the bundle to thecorresponding twister or fastening device. Fig. 5' is a bottom plan viewshowing the mechanism for operating the binding devices. Fig. 5 is aplan view showing details of the twister driving gear. Fig. 6 is ahorizontal section on the line yy, Figs. 1, 2 and 3. Fig. 7 is a faceView of one of the twisters, the adjacent wall of the bale chamber beingshown in vertical section. Fig. 8 is an edge view of the same. Fig. 9 isa plan view of a twister and attendant parts, showing the manner inwhich the ends of the bands are united and the bands severed. Fig. 10 isa vertical section on the line zz, Fig. 8. Fig. 11 is a diagramillustrating the binding operation.

Referring to the drawings,A represents a horizontal trunk or chamberinto which the material is delivered at one end through a top-opening ata, and from which the bales are delivered at the opposite open ,end,-a'.

B represents the reciprocating plunger or traverser by which thesuccessive charges are forced forward past the retaining dogs 0, andadded to the previously accumulated mass.

The foregoing parts are of ordinary construction.

In applying my improvement I locate close to oneside of the trunk in avertical line,

two, three or more rotary twisting devices D, adapted, as presentlydescribed, to unite the ends of the applied binding wires. At theopposite side of the trunk I mount a corresponding number ofhorizontally-movable needles E, intended to carry the wires through thetrunkfrom sideto side between the ends of the adjacent bales and presentthem to the action of the twisting devices. Suitable reels or otherwire-holders, F, corresponding in number with the twisters are locatedon one side of the machine, and a like'number of reels or holders, F,are located on the opposite side. The wires are laid from the reels Fover the ends of the corresponding needlesand thence through and acrossthe trunk to the corresponding twisters at the opposite side. The wiresfromthe reels F, are laid directly to the twisters on the same side ofthe machine.

In order that the operation of the foregoing parts and the details tofollow, may be more fully understood, attention is directed to Figs. 6and 11, which disclose the general mode of action. The mass ofcompressed material divided into suitable lengths or bales byintervening boards as usual, progresses through the trunk in thedirection indicated by the arrow. When the line of separation betweentwo bales arrives opposite a needle the latter advances through thetrunk and passes the wire between the bales in a double or looped formto the twister at the opposite side as shown in Fig. 6, the course ofthe wire being also indicated on the extremeright in Fig. 11. When thewire thus passed between the bales reaches the twister the latteroperates and unites the wire which has just entered from the oppositeside with the wire entering on the side where the twister is located,thus uniting the two wires as shown, at the middle, in Fig. 11. Thecutter then actsto sever the twisted portion at the middle of the twist,leaving the forward bale completely surrounded by the two wires as shownon the left hand in Fig. 11, the one wire extending as shown, aroundthree sides of the bale, and being connected at its extremities by theshorter wire extending along the fourth side. The binding operationbeing completed and the applied bands severed,the mass advances step bystep the length of one bale, causing the remaining or unsevered wires tobe eX- tended lengthwise of the second bale, after which the needleadvances as before, carrying the one wire between the bales to itscompanion on the under side, that the twister may again complete thebinding action.

Each twister consists of a beveled pinion, D, supported by a horizontaljournal, d, in a rigid bearing, (P. The bearing, the journal and thepinion are slotted in an axial direction from one sideinward to thecenter, or, in other words, slotted radially, as shown in Figs. 7 and10, the slots being of a width equal to the diameter of the-wire so thatwhen two wires are laid side by side therein, and the pinion rotated,the effect will be to twist the wires together above and below thepinion, as shown in Fig. 9. -In order that the pinions may grasp thewires and direct them into the slots with certainty, I provide them withhooklike arms, d extending outward and forward from the rear wall of theslot, which arms, passing through the notched ends of the needles, pickup the wires carried forward by the latter and carry them up over therounded bearings (1 The wires so picked up, being under tension, enterthe radial notches in the pinions D, and when they reach the openings inthe bearings d they drop down into the hub d, upon the wires passing atthe opposite side of the trunk, which are already in said hubs. Thegrooves in the hubs being only wide enough to admit a single wire itfollows that by the rotation of the twist-er the two wires therein arewound or twisted together at both ends of the hubs, as represented inFig. 9. The wires passing along the side of the trunk on which thetwisters are located pass on the outside from the spools to the openingsopposite the twisters and then pass through said openings to the inside,as represented in Fig. 6. Thus, when the wires are severed after beingtwisted together the succeeding bale, as it is formed and advanced,draws the connected wires forward. As the bight of the wire is carriedoutward by the rotation of the arm 61 it rides against the open roundedside of the bearing 01 shown in Figs. 8 and 9,which acts to open orspread the bight or looped end of the wire in a vertical direction sothat it will ride over the bearing and pinion and enter the slottherein.

The severance of the wire after the completion of the twisting operationmay be effected by a knife of any suitable construction, but Irecommend, as shown in Figs. 3

and 9, knives d pivoted at d to fixed supports, and arranged to moveclosely over the face of the respective pinions so that the united wiresare severed between the two twists, leaving the two wires whichconstitute each band united.

Referring now to the needles for passing the wires across the ends ofthe bales and presenting them to the twisters, attention is directed toFigs. 3 and 4:, in which it will be observed that the inner end of theneedle is notched vertically and also slotted horizontally to admit aperipherally-toothed wheel, 6, mounted to turn on a vertical pivottherein. The wheel having the notched teeth to sustain and carry thewire serves all the purposes of an ordinary anti-frictiondevice orsheave, allowing the wire to pay smoothly and easily around the end ofthe needle, while at the same time, the space between the teeth beingexposed by the notch in the end of the needle admits of the hook on thetwister passing in between the teeth and behind the wire so as to graspthe same with certainty.

For the purpose of driving the twisters, the needles and the knives, Imount on the under side of the frame or trunk in any suitable guides, alongitudinally-reciprocating frame H, which I denominate the rackframe.This frame is provided with an operating pitman, 71, adapted to beconnected to the plunger or traverser at will, so that it' may becarried to and fro thereby as hereinafter described in detail.

The rack-frame is provided on one side with a rack-bar h engaging asemi-circular pinion, 773, on one end of a vertical shaft, 71. in fixedbearings. This shaft carries at its upper end a crank-arm, 72/ and thepinion 71. is pro' vided with'a corresponding crank-pin. The crank-armand crank-pin are connected, as shown in Fig. 3, by the pitman h, toopposite ends of an upright bar, 71. to which the outer ends of all theneedles E, are attached so that as the rack-frame is moved to and fro itcauses the needles to be thrust through the trunk or bale chamber andretracted.

The twisters receive motion in the manner following: A second rack, 71on the rack-frame engages a pinion, h, on the lower end of a verticalshaft, h mounted in a fixed bearing. The shaft, h is provided on thelower end with a fly-wheel and is connected by a beveled gear with apinion, It, on the bottom twister.-

The pinion h instead of being fixed on the shaft h is mounted. looselythereon, and provided, as shown in Figs. 3 and 5, with a pawl 71, whichengages a ratchet wheel, h, on the shaft. The arrangement is such thatthe pinion is permitted to turn while the twister remains at rest duringthe outward or backward movement of the plunger and rack-frame. Thebottom twister in turn communicates m0- tion through beveled pinions hit, and their connecting shaft 71, to the middle twister. The middletwister in turn communicates mo tion in like manner through gears h h,to

eeaeas 'top and bottom, as shown in Fig. 3. In order to secure a properaction it is found advisable to have the angles or corners formed by thejunction of the horizontal and vertical walls filled out or rounded. Toavoid the great expense of rolling the main sheets into suitable formfor this purpose I have adopted filling pieces a ,which are insertedbetween the horizontal plates and the flanges on the vertical plates,the inner edges of these pieces which are exposed within the trunk beingrounded so as to fill the angle as shown in the drawings.

The operation ofthe series of knives is effected by a verticalgravitating bar, d, to which they are all pivoted at their tail ends,the bar being provided'at its lower end as shown in Figs.- 3 and 5, witha roller d? which is acted upon and raised at the proper time by aninclined arm or cam, (:1 projecting rigidly from the reciprocatingrack-frame. It will thus be understoodfrom the foregoing descriptionthat the twisters begin to rotate with the forward movement of theneedles, and that the first rotation carries thewire on that side overthe bearing and into the slot in the twister, the latter merelyrevolving around the wire without twisting it. Assoon, however, as thewire carried'forward by the needles from the opposite side comes withinreach of the arm d", it is picked up and carried over and caused toenter the twister, as already explained, and this occurs at the instantthat the rack-bar and needles reach the limit of their forward movementand when the action of the pawl and ratchet mechanism h 71. also ceases.It is evident that without some provision for continuing, the

rotation of shaft h, the twisters would also stop before twisting thewires together. Hence I place a fiy-Wheel h on the shaft 71 the momentumof which revolves the shaft and twisters a sufficient number of times toform the twists after the driving force ceases to act.

The plunger or traverser is required to reciprocate rapidly andconstantlywhile the.

binding devices are to be brought into action only at comparatively longintervals. It is for this reason that the connection between the plungerand rack-frame is placed under the control of the operator as beforementioned. The most simple and preferred arrangement to this end is thatrepresented in Figs. 1 and 2, in which it will be observed that thepitman h, is provided at one end with a vertical stud, h, to enter anarm on the plunger from the lower side. A lever, h mounted on theframelies at one end beneath the pitman which slides longitudinally thereon.The opposite end of the lever is-controlled by a vertical rod h mountedin guides on the main-frame and under the control of the attendant. Whenthis rod is depressed so that the lever will raise the pitman the studon the latter will engage with the plunger and cause the rack-frame andplunger to move together, but when the lever is released it permits thepitman to fall out of engagement so that the rack-frame and the entirebinding mechanism connected therewith'may remain at rest until asufficient quantity of material has accumulated to form another bale.duced between the lower end of the rod and the lever to preventexcessive pressure being applied through the lever to the pitman, butthis is not a necessary feature.

The detaining dogs 0 are subjected toa severe lateral pressure by thereaction of the hay against them,and as ordinarily mounted it is foundthat they are liable tobind and fail to move in the proper manner. Toovercome this difficulty I adopt the construction shown inFig. 6. Eachdog is in the form of a horizontal bolt having one end beveled andprojected inward through the wall of the trunk. At the outer end itslides through a stationary guide and at the inner end it is'connectedby a vertical pivot, 0 to one end of a horizontal link, 0 which is inturn connected by a vertical pivot to a frame. This gives the boltastrong lateral support but avoids side friction thereon and permits itto move endwise in a smooth and easy manner. A spiral spring, 0, appliedaround the upperend of the dog urges it constantly inward. At the innerend each dog is formed with an open horizontal slot, as shown in Fig. 3.The binding wires are laid through these slot-s which serve to guidethem and also to prevent them from getting into such position as to bepinched or cut by the ends of the plunger.

The operation of the binding apparatus is as follows: During theaccumulation of the bale the pitman his out of connection and thebinding devices remain at rest. When the proper time arrives for thebinding of the bale the operator, depressing the rod, h

against thelever it, causes the lever h, to lift the pitman intoengagement with the plunger whereupon a rack-frame is moved to and froand caused to operate the binding devices. During the retreat of theplunger from the compressed material the needles are thrust. through thetrunk so as to present the wires across the end of the completed bale tothe twister at the opposite side. During this action the twisters owingto the existence of the ratchet mechanism in the driving train, remainat rest, but the instant that the plunger starts forward again thetwisters revolve and unite the wires, after which they are severed.

A spiral spring, 71 is commonly intro- Owing to the fact that the needleoperating pitmen, h, stand practically upon the center the needlesremain at rest or practically so momentarily and until the twisters havegrasped the wires presented by them. The entire binding operation isperformed by a single forward and backward movement of the plunger,after which the binder driving pitman is again disengaged. The fly-wheelon the lower end of the pinion driving shaft serves to continue themotion of the twisters after the action of the driving-frame ceases,wherebythe wires are the more firmly united.

Having thus described my invention, what I claim is- 1. In abaling-press, the trunk and plunger, in combination with thereciprocating rackframe connected with, and operated by the plunger, thecrank-shaft geared with the rackframe, the transverse binding needles,and pitmen connecting the same with the crankshaft, whereby thereciprocations of the rackframe rotate the crank-shaft and operate theneedles, the twisters also geared with, and driven by, the rack-frame,and cutters adjacent to the twisters for severing the Wires.

2: In a baling-press, the combination with the trunk and plunger, of thereciprocating rack-frame connected with, and operated by, the plunger,the crank-shaft geared with the rack-frame, the reciprocating needles,and pitman connections between the cranks and needles, whereby thelatter are reciprocated, the twisters also geared with the rack-frame,the cutting devices adjacent to the twisters,

and a cam-arm on the rack-frame for operat ing the cutters.

3. In combination with the trunk and plunger, the reciprocatingrack-frame detachably connected with, and operated by, the plunger, thecrank-shaft driven by the rack-frame, transversely moving reciprocatingneedles coupled to the cranks of the shaft, the twisters geared with,and operated by the rackframe, and means for disconnecting the rackframefrom the plunger and again connecting the same.

4. In a baling-press, a needle notched across its end and slotted in aplane at right angles to the notch, a toothed wheel pivoted or journaledin the slot, the ends of the teeth being notched for the reception ofthe binding wires, in combination with a rotary twister having an armadapted to pass through the notch ot' the needle and between the teethof the wheel therein, to take up the binding wire, substantially asshown and described.

5. In combination with a slotted twister wheel substantially as shown, abinding needle, provided at its end with the wheel having the teeth withnotched ends to present the wire to the twister.

In testimony whereof I hereunto set my hand, this 9th day of April,1889, in the presence of two attesting witnesses.
